CONDENSER FOR STEAM-ENGINES.

Specification of Letters Patent No. 15,663, dated September 2, 1856.

combining within the condenser between aseries of condensing plates orsurfaces the united condensing action of both jets of water and ofcurrents of atmospheric air in the manner substantially as presently described.

The construction of my improvement is as follows, reference being had tothe annexed drawings in which- Figure 1 is a top view of the steamboiler and condenser, with part of the boiler and condenser removed toshow a portion of the interior of the condenser. Fig. 2 is a side Viewof the boiler, and condenser in section with its upper part in brokenview to show the rose pipe, and in both figures like letters refer tolike parts.

A is the steam boiler and its smoke box of any usual form.

B, is the condenser consisting of a series of vertical fiattubesconnected in front to and extending below the steam receiving cylinder Cand at their back ends connected to the condensed steam or waterreceiving cylinder D. These flat tubes are at right angles to the axisor centers of these two cylinders, and incline toward D to let the waterrun into it. These flat tubes also are connected together by numerousshort horizontal cylindrical tubes 9 extending between them, andanswering also as stays to prevent collapse, as well as givingadditional condensing surface. Inside of the upper part of each of theseflat tubes is extended a perforated water or jet pipe 6 running thewhole length of the flue, and all of these jet pipes connect in front toa cross supply pipe W into which is discharged the supply of injectionwater for these rose pipes. These tubes and cylinders are surrounded byan outside casing K and by means of the blower H and its nozzle z or byvelocity and a funnel shaped mouth in front of the engine or on the boatatmospheric air in a cool state is forced in and through the spacesbetween the fiat fiues and cross tubes or stays of the condenser andthus condenses the steam or aids the water in condensing the steam, andbecoming heated passes back to assist the furnace, through pipe S. Theinjection water used in cross pipe W' and in the rose pipes 6 comes incontact with the steam which passes from the engines cylinders throughthe pipes X into the receiver G and condenser B where it is condensedand runs into the bottom of the receiver D from which it is extractedthrough pipe U. Vapor of bi-sulfuret of carbon may be condensed by thiscondenser, in which case the water will be extracted through pipe T andthe bi-sulfuret through pipe U. The water from the receiver D may beforced by means of a double acting force pump through a series ofcooling pipes so that it returns to the jet pipes cool and underpressure for repeated use.

Y is an exhaust pipe with a floating valve held down by the pressure ofthe atmosphere and only operating to exhaust up the chimney in case thecondenser fails to condense from any accidental cause, or is shut ofiand the engine used as high pressure.

What I claim is The combination of the fiat vertical tubes i connectedby horizontal tubes with rose pipes inside and surrounded by the outercase to condense by the combined action of air and water, substantiallyas described.
